I try to limit myself to answers that I don't think that anyone else here would come up with. I admit to not always succeeding in that, but I have been pleasantly surprised at how often I can do that. Even if a question has been answered, there may be a way to bring up something important that the existing answers don't.

I think it is good if higher level monks try to do that. As chromatic says, why deprive others of the valuable learning experience of trying to answer people's questions?
